Population Assessment of Tobacco and Health (PATH) Study [United States] Restricted-Use Files

The PATH Study was launched in 2011 to inform the Food and Drug Administration's regulatory activities under the Family Smoking Prevention and Tobacco Control Act (TCA). The PATH Study is a collaboration between the National Institute on Drug Abuse (NIDA), National Institutes of Health (NIH), and the Center for Tobacco Products (CTP), Food and Drug Administration (FDA). The study sampled over 150,000 mailing addresses across the United States to create a national sample of tobacco users and non-users. 45,971 adults and youth constitute the first (baseline) wave, Wave 1, of data collected by this longitudinal cohort study. These 45,971 adults and youth along with 7,207 "shadow youth" (youth ages 9 to 11 sampled at Wave 1) make make up the 53,178 participants that constitute the Wave 1 Cohort. Respondents are asked to complete an interview at each follow-up wave. Youth who turn 18 by the current wave of data collection are considered "aged-up adults" and are invited to complete the Adult Interview. Additionally, "shadow youth" are considered "aged-up youth" upon turning 12 years old, when they are asked to complete an interview after parental consent. At Wave 4, a probability sample of 14,098 adults, youth, and shadow youth ages 10 to 11 was selected from the civilian, noninstitutionalized population at the time of Wave 4. This sample was recruited from residential addresses not selected for Wave 1 in the same sampled PSUs and segments using similar within-household sampling procedures. This "replenishment sample" was combined for estimation and analysis purposes with Wave 4 adult and youth respondents from the Wave 1 Cohort who were in the civilian, noninstitutionalized population at the time of Wave 4. This combined set of Wave 4 participants, 52,731 participants in total, forms the Wave 4 Cohort. Please refer to the Restricted-Use Files User Guide that provides further details about children designated as "shadow youth" and the formation of the Wave 1 and Wave 4 Cohorts.

PATH 研究（PATH Study）始于2011年，旨在为美国食品药品监督管理局（Food and Drug Administration, FDA）根据《家庭吸烟预防与烟草控制法》（Family Smoking Prevention and Tobacco Control Act, TCA）所进行的监管活动提供信息。PATH 研究 由国家药物滥用研究所（National Institute on Drug Abuse, NIDA）、美国国立卫生研究院（National Institutes of Health, NIH）和食品药品监督管理局烟草产品中心（Center for Tobacco Products, CTP）联合开展。研究对美国国内超过15万个邮寄地址进行了抽样，以构建一个全国性的烟草使用者与非使用者样本。该研究的第一波（基线）数据收集包含了45,971名成年人和青少年。这45,971名成年人和青少年以及7,207名“影子青少年”（在第一波中抽取的9至11岁青少年）共同构成了53,178名参与者的第一波队列。受访者被要求在每个后续波次完成一次访谈。至当前数据收集波次时年满18岁的青少年被视为“成年化成人”并受邀完成成人访谈。此外，“影子青少年”在年满12岁时被视为“成年化青少年”，在此之后，在获得父母同意的情况下完成访谈。在第四波时，从第四波时的民间、非机构化人群中选取了14,098名成人、青少年和10至11岁的“影子青少年”的概率样本。此样本是从未在第一波中选中的相同抽样PSU和段落的住宅地址中，采用类似的户内抽样程序招募的。这一“补充样本”在估计和分析目的上与第四波来自第一波队列的、当时处于民间、非机构化人群中的成人及青少年受访者相结合。这一综合的第四波参与者集合，总计52,731名参与者，构成了第四波队列。请参阅《受限使用文件用户指南》，其中提供了关于被指定为“影子青少年”的儿童以及第一波和第四波队列形成的更多详细信息。数据集0001（DS0001）包含了主链接文件的数据。此文件包含42个变量和67,276个案例。该文件提供了每个人的唯一识别号码以及每个波次中他们的受访者类型的主列表。数据集1011（DS1011）包含了第一波成人问卷的数据。此数据文件包含2,021个变量和32,320个案例。每个案例代表一次单独完成的访谈。数据集1012（DS1012）包含了第一波青少年（及父母）问卷的数据。此文件包含1,431个变量和13,651个案例。数据集1411（DS1411）包含了第一波成人状态标识符数据，具有5个变量和32,320个案例。数据集1412（DS1412）包含了第一波青少年（及父母）状态标识符数据，具有5个变量和13,651个案例。每个状态标识符数据集中都包含相同的5个变量，包括PERSONID（用于将状态标识符与问卷和生物标志物数据链接）以及3个变量指定州（州FIPS、州缩写和州全名）。数据集2011（DS2011）包含了第二波成人问卷的数据。此数据文件包含2,421个变量和28,362个案例。在这些案例中，26,447人也完成了第一波成人问卷。其余1,915个案例是之前已完成第一波青少年问卷的“成年化成人”。数据集2012（DS2012）包含了第二波青少年（及父母）问卷的数据。此数据文件包含1,596个变量和12,172个案例。在这些案例中，10,081人也完成了第一波青少年问卷。其余2,091个案例是之前作为“影子青少年”被抽取的“成年化青少年”。数据集3011（DS3011）包含了第三波成人问卷的数据。此数据文件包含2,359个变量和28,148个案例。在这些案例中，26,241是继续完成先前成人问卷的成年人。其余1,907个案例是之前已完成青少年问卷的“成年化成人”。数据集3012（DS3012）包含了第三波青少年（及父母）问卷的数据。此数据文件包含1,492个变量和11,814个案例。在这些案例中，9,769是继续完成先前青少年访谈的青少年。其余2,045个案例是之前作为“影子青少年”被抽取的“成年化青少年”。数据集3111、3211、3112和3212（DS3111、DS3211、DS3112和DS3212）的内容暂未提供。
